Annual Cleaning: Wipe down frames to get rid of contaminants and salt (if near the coast).Hardware Lubrication: Apply a drop of oil to pulleys and locks every 12 months.Paint Inspection: Check for cracks or chips in the surface every 2-- 3 years to prevent rot.Clearing Cills: Ensure the bottom cills are devoid of debris to enable water to run off efficiently.Regularly Asked Questions (FAQ)1.
